Administration of the MapR Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter
options. MapR Database administration is associated with tables, columns and column families, and table regions.

The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight
client applications and the MapR cluster. This section describes considerations when upgrading the service, how to modify
configuration settings, and how to administer and manage the service.

fcdebug

The fcdebug utility can be used to dynamically set the loglevel to debug a library.

The core-site.xml file can be modified to set the loglevel of all modules
using the fs.mapr.trace property. However, FUSE must be restarted for the
change to take effect. The fcdebug utility allows you to debug a specific
library (at runtime) without restarting FUSE.
